Help! I can't capture on my Avid Xpress Pro 4.5

I've just got myself a brand new system for my Avid Xpress Pro and have installed it and it seemed all fine until I went to capture and the capture menu wasn't highlighted!
I'm using Sony DCR-VX2000E camera as well as DSR-250P but when I went to configure the decks in the configuration menu, they had all other Sony camera models except the ones i've got?!
I can capture and edit on my Adobe Premier fine so I think I'm doing something wrong with the Avid software setting..
Does anyone know what I'm doing wrong? Your advise would be much appreciated. Thank you!
